ACETYLENE-LAM P.

SPECIFICATION forming part of Letters Patent No. 620,149, dated February 28, 1899.

Application filed December 22, 1897. Serial No. 663,407. (No model.)

' T on whom it may concern.-

Be it known that I, JOHN GEORGE AULsE- BROOK KITCHEN, a subject of the Queen of Great Britain, residing at Manchester, in the county of Lancaster, England, have invented certain new and useful Improvements in Acetylene-Lamps, of which the following is a specification.

This invention relates more particularly to portable acetylene table and vehicle lamps; and it consists in an improved construction of generator for producing acetylenefrom calcium carbid and water, the chief objects of the improvements being to obtain better control over the production of gas and safety from explosion.

My improved generator is constructed in accordance with that system in which the carbid is contained in a vessel above the vessel containing the water and the necessary moisture to cause decomposition of the carbid and the production of the acetylene is conducted to the carbid 0n the principle of capillary attraction by means of some absorbent material.

The drawings attached hereunto illustrate the carrying out of my invention.

Figure 1 represents a side elevation of a vehicle-lamp with the improved generator; Fig. 2, asectional elevation of the generator as seen from the back with the lamp removed, and Fig. 3 a sectional plan of the generator sectioned at the operating-shaft.

In the several views the like parts are indicated by similar letters of reference.

Referring to the figures, my improved generator has a lower compartment a, formed to contain the reactionary liquid, an upper compartment b, which is preferably made detachable, and a loosely-fitting vessel 0 to contain the calcium carbid. The compartment 1) is fitted with a lid 1), preferably hinged, having a spring-catch b and'is made gas-tight by a flexible packing or washer 17 It is secured is a central orifice c.

vessel there is formed a groove cl, into which is fixed a rack 01, there being sufficient width in the groove for a pinion d to travel up and down. The pinion d is mounted in position upon a spindle 01 which is carried in a bearing formed by the stuffing-box (Z upon the exterior of the compartment b. The outside end of the spindle d is provided with a milled disk 61 by which the vessel c can be lowered and raised. There is a gas-outlet conduit e leading from the upper part of the compartment 2) to the burner-socket f, which in the case of a vehicle-lamp is mounted in front, say, of the compartment Z). That part of the conduit 6 lying against the compartment b is undercut, forming a dovetailed ridge, as shown in Fig. 3. The hood g of the lamp is formed with a groove 9' to fit the dovetailed ridge and the hood is held in position by passing the groove on the dovetailed ridge. Any other suitable means may, however, be employed for securing one part to the other. The burner-socket f has a screwed cap f fitted beneath, by which the burner can be easily cleaned by blowing through or by passing a wire through.

The lamp illustrated in Fig. 1 is provided with a spring-carrier h of well-known construction, which is attached to a saddle-piece h, fixed to the compartment 1). Any other suitable carrier may be similarly attached.

The compartment b is provided with a bottom b in the center of which there is a tube 19 The bottom of the vessel 0 or carbid-receptacle is preferably flat and its orifice 0' large enough to pass over the edge of the tube 19 Into the tube 12 is fitted a Wick 2', which projects above the edge anddepends into the vessel a and may be fixed in position by a pin 19 The production of gas is commenced in this apparatus by lowering the vessel 0 until the wick passes through the orifice c in the vessel c and comes in contact with the carbid, when gas is produced due to the moisture communicated by the wick from the water in the vessel (1. The production of gas is practically stopped by raising the vessel 0 by means of the spindle 01 clear of the wick i.

When the carbid in the lower part of the vessel c is exhausted and the resulting lime-dust does not carry the moisture in a sufficient quantity for maintaining the generation of gas to the carbid in the upper part of the vessel c, the latter can be lowered till the top of the wick-tube is pushed through the lime-dust and the Wick comes into contact With the upper layers of carbid. it

According to requirements, the relative lengths of the wicktube and carbid vessel may be varied from the proportions shown on the drawings.

I claim as my invention A Vehicle acetylene-lamp consisting of the combination of a lower liquid-containing compartment, an upper compartment, attachable and detachable therefrom, and communicating by means of a wick-tube with the lower compartment, the upper compartment having at its upper end a hinged lid and catch therefor, a loosely-fitting carbid-containing vessel compartment, substantially as and for the purpose described.

In testimony I have hereto affixed my signature in the presence of two Witnesses.
